` Curr BUT'rdN;

Application' med april `'4,

lily invention relates to improvements-in cuifbuttonspand itconsists inthe combina.- tions, constructions, andE arrangements herein describedand claimed. y

An object of my invention is to provide an improvement over my PatentNo. 1,56 l,- 657, issued'December 8,1925, and my co-` pendingapplication, Serial blo.A 111,353, Vfiled May 24, 1926, andl'allowedNovember 27, 1926.` The improvement consists in provid ing devicewhicli.isymore eiiicient forthe purpose intended, andwliich ismore certain inoperation.

A further object of' my'invention is to pro vide a device of the'type'described in which the cooperating parts when pressedtogetlier slightlybecome engaged"7 and when pressed together morefirmly will be released yA further object of "inventionis to'provide a device/of the 'typedescribed in'wllich the parts cannotbe `disengaged but become more'firmly locked together whelrforce applied to pull them apart. 'y

A further object'of my invention is yto` provide a'device ofthetyped'escribedl which has novel means for retardingzthe movement of thelocking mechanism for permitting tlie cooperating parts tofbe releasedfrom one another whenV pressed toward eachother.

t Other `objectsand y A in the following specification, and lthe novelfeatures ofthe invention willl vbe particu larly pointed out intheappended claims.`

My invention is killustrated in the accom-V panying` drawings, 4formingpart of this application, in which Figure l is spaced-apart views of themale and female members of my cuff button, the female member being shownin section,

Figure 2 is a sectional view of my cuil button with the cooperatingparts engaged,

Figure 3 is a sectionalview of my cuil button with the cooperating partsin position for disengagement, and y Figure 4 is a section along theline 1 -4:

In carrying out my invention l provide a male member A and a femalemember B. The male member A is provided with a reduced portion l havinga shoulder 2 and a frusto-conical head. The reduced portion l tapersinwardly toward the head 3 providing a 'recess 4. A washer 5 is disposedconcentric with the reduced portion l and normally held in engagementwith the shoulder 2 by means of a compression spring advantages willappear isf/zr;` sex-iai No. meses.

Thellfemale member `BL is (provided `with a centralfopening S, 'tliewalls ofwliiclitaper outwardly.4 Diametrically-opposed' guide!" Y ways 9-are disposedJ inthe wall1 of the openi inge. lAsleeve iOflias cuts-'l1for a portion of its'lengtli equally spacedtherearouiid and'- forming aplurality of prongs 121 The prongs 'l2l arel provi-ded withi inwardlyex# tending integral lugs 133; The sleeve lOisVV providedat its lowerlextremity, view-ing Figures '1, 2 and '3, with acircumferentiallydisposed groove lll' which eXtendsth-rough the prongsv12,-land inl-,which is disposed-"a` resilientA retaining* members 1Garef integral' with they sleeve l() and receivable in -the guideways 9.The outer 'extremities of the' 1guifde'tv:iys 9' are smaller `than thediameter of the' retaining members- 16, thus providing `a-stopi for'ther retainingmembers;l t

Aspreading ring 17 "is centrally mounted upona cover'll.A The cover 18is secured to,l

ring Diametri"ally-opposed i 75 the female member B by `any `suitablemeans; The spreadinggring 17 is"provided with an arcuate-shapedengaging'surface 19.v

From the foregoing description-vof the variousV parts of the device,ztheA operation thereof may be readily understood. The mal'e memberAfandl tlie female member. B" are inserted' in the cuff 4ofashirt'sleeve in preciselylthesanie nia-mieres the ordina-ry type ofseparable cuiff linie-s,- whereupen the reduced portion l of the male`member is projected into 'the sleeve l() of the female member. Byslight pressure inwardly uponl the male andv female members, the memberswill be moved into the locked position shown rate the male and femalemembers by pulling outwardly thereupon, the prongs `12 will engage withthe wall of the opening 8 and more permanently lock the memberstogether.

lf the user is desirous of disengaging the male and female members, hemay do so by 1 in Figure 2. If the user endeavors to sepa- 4 ing thismovement, the sleeve 10 is rotated and the prongs 12 are forcedoutwardly by their engagement with the arcuate-shaped surface 19 of thespreading ring 17, see Figure 3. The outward movement of the prongs 12moves the integral lugs 13 free from the annular recess 4. By releasingthe male and female members, the compression spring G which is inengagement with the male member A and the washer 5 forces the malemember free from the female member. By releasing the male and femalemembers, the sleeve lO is also free to move outwardly, but is checked inits outward movement by the engagement of the retaining members 1G withthe walls of the slots 9. Therefore, the speed of the travel of the malemember away from the female member is greater than the speed of thetravel of the sleeve 10 outwardly. The resilient ring l5, together withthe resiliency of the prongs 12, is the means for moving the sleeve l0outwardly.

I claim:

l. A entf button of the type described comprising a male member, a headportion for said male member, said male member having an arcuate-shapedgroove adjacent said head portion, a female member having anarcuateshaped groove extending downwardly therein, a sleeve carried bysaid female member, a retaining member integral with said sleeve andreceivable in said groove, and retaining lugs receivable in the recessin said male member for locking said male member to said female member.

2. A cuff button of the type described comprising a male member, a headportion for said male member, said male member having an arcuate-shapedgroove adjacent said head portion, a female member having anarcuateshaped groove extending downwardly therein, a sleeve carried bysaid female member, ay retaining member integral with said sleeve andreceivable in said groove, retaining lugs receivable in the recess insaid male member for locking said male member to said female member,prongs integral with said sleeve, said retaining lugs integral with saidprongs, and means adapted to force said prongs outwardly for removingsaid integral lugs from said recess` for freeing said head portion andsaid male member when said male member and said female member are forcedinwardly a. predetermined distance, said retaining member being movedwithin said slot and rctarding the movement of said sleeve, said prongs,and said retaining lugs into their normal posit-ions.

il. A device of the type described comprising a male member, a reducedportion integral with said male member, a head portion integral withsaid reduced portion, said reduced portion having a recess disposedadjacent said head portion, a female member having an opening therein, asleeve movably disposed in said opening, retaining members integral withsaid sleeve and receivable in arcuate-shaped inwardly extending slots insaid female member, resilient prongs integral with said sleeve, aresilient ring carried by said prongs, inwardly extending retaining lugsintegral with said prongs and receivable in said recess when saidreduced portion is disposed within said sleeve a predetermined distance,means for forcing said prongs and said retaining lugs outwardly forfreeing said head portion when said male member and said female. memberhave been moved inwardly a }nedetermiiual distance, and means disposedconcentric with said reduced portion for forcing said male member andsaid reduced portion free from said sleeve and said female member, saidretaining members retarding the movement of said sleeve, said prongs andsaid retaining lugs into their normal positions.
